title: Laparoscopic resection of benign hepatic cysts: a new standard.
abstract: BACKGROUND
  We sought to evaluate the feasibility and outcomes of laparoscopic resection of symptomatic hepatic cysts.
  
  
  METHODS
  Fifty-one patients underwent laparoscopic resections for symptomatic hepatic cysts. Resection was accomplished laparoscopically with an Endo-GIA vascular stapler. Data were collected in a prospective database.
  
  
  RESULTS
  Median patient age was 60 years, with a median lesion diameter of 13 cm. Indication for surgical treatment was pain in 92% of patients. Laparoscopic resection was successful in 100% of patients. A pure laparoscopic approach was used in 58% of patients, the remaining used a hand port. Median operating time was 178 minutes. Preoperative diagnosis was polycystic liver in 88% and simple cyst in 12% diagnosed by preoperative imaging. Histologic examination showed 90% to be simple cysts and 10% cystadenomas. There were nine minor perioperative complications. Median hospital stay was 2 days. Relief of symptoms was achieved in all patients operated on for pain, with a median followup of 13 months. Two patients required reoperation for recurrence of the same cyst. CT or MRI was used for yearly followup.
  
  
  CONCLUSIONS
  Laparoscopic resection of symptomatic liver cysts is a feasible and effective method to relieve symptoms with minimal surgical trauma. This series represents the largest report of laparoscopic management for benign hepatic cysts and provides evidence for a routine laparoscopic approach to benign symptomatic cysts. Traditional surgical methods should be reserved for when a malignancy is expected, laparoscopy is contraindicated, or for recurrence after an initial laparoscopic approach.
